Hook Ups

Jennifer Lopez and her 24-year-old boyfriend Casper Smart were quite the lovebirds and enjoyed a Valentine's Day frolicking on the sand in Santa Barbara on Tuesday.

Besides holding hands and taking long walks on the beach, Jen even climbed up on top of Casper to ride the swing together.

New York Jets interception-machine Mark Sanchez might actually have done something right this year ... and her name's Kate Upton -- this according to the super model herself.

Rumors have been spreading like wildfire ... Mark and Kate are an item -- but we asked the buxom Victoria's Secret angel straight up ... are you single ... and she played coy, replying, "What do you think?"

We pressed a little more ... asking if Mark was the mystery man -- Kate hedged, responding, "I don't know!"

As for the real truth -- Kate tells us, "It's whatever you think!"

So here's what we think -- if Mark had any game, he would have AT LEAST made the playoffs.

Love is in the air this Valentine's Day... and these celebs aren't afraid to show a little PDA. Can you guess which stars are behind these puckered pics?

Kim Kardashian has REUNITED with her ex-boyfriend Reggie Bush ... breaking bread with the NFL player at the Beverly Hills Hotel this weekend ... TMZ has learned.

Multiple sources tell us ... the two were smiling and laughing during the lunch date ... and played it cool when fans approached them for pictures and autographs.

We're told it seemed just like old times ... before Kim went off and married/divorced that other guy whose name we can't remember.

George Clooney ... plus Stacy Keibler ... plus an air horn ... equals practical joke caught on tape ... and it's hilarious.

Although "Dexter" co-stars Michael C. Hall and Jennifer Carpenter finalized their divorce in December, the former couple couldn't be any closer as they walked arm-in-arm and snuggled in Venice Beach on Wednesday.

Call him Mitt "Love Glove" Romney ... 'cause TMZ has learned a condom company has officially launched a line of special rubbers dedicated to the Republican candidate ... despite not having Mitt's approval.

The condom company launched a website this week, offering the political jimmys for roughly five bucks a pop.

TMZ spoke with the owner of the company -- which also famously launched Obama condoms a while back -- who tells us he KNOWS his operation is perfectly legit because a State Supreme Court judge previously ruled his products are protected under his First Amendment right to free speech.

Although rumors of his dating escapades have swirled since he split from Kim Kardashian, sources close to Kris Humphries tell TMZ ... he has no plans to date anytime soon.

According to our sources, Kris has not dated anyone since his breakup from KK. We're told Kris has not gone out on a single date and right now his only focus ... is on basketball.

And it's working so far -- Kris is averaging career highs in points, rebounds, assists, blocks and steals.

Whitney Houston and Ray J sure seemed very couple-y outside a restaurant in West Hollywood last night -- because when it came time leave, Ray J was the PERFECT gentleman.

As the two were leaving Le Petit Four on Sunset Blvd last night, Ray J opened the door for Whitney, made sure she was safely snuggled inside, and then shut the door for her. Chivarly ain't dead!

The mystery is over ... Steve-O and Elisabetta Canalis are DEFINITELY more than friends ... and yesterday they engaged in a little mouth-on-mouth PDA to prove it.

There was a fierce debate in our newsroom ... some people felt that Elisabetta's decision to date the "Jackass" star is a step down from George Clooney. Others think she's decided status symbols don't bring happiness ... and since she might be happier with Steve-O, it's NOT a step down.

So, we gotta ask ...

Elisabetta Canalis and Steve-O went to a HAIR SALON this weekend ... TOGETHER ... so, it's fair to assume they're totally dating now, right?

Rumors have been swirling for weeks ... that George Clooney's ex-GF and the "Jackass" star have been getting pretty up close and personal in the past few weeks.

The two hit up Trust Hair Salon in West Hollywood on Saturday ... and as they both got into Steve-O's car ... we asked if they were officially more than friends.

Michaele Salahi and Neal Schon have no problem flaunting their love, and now they've found a new way to do so ... in the form of a music video.

The new video will be for the Journey song "Resonate" and was filmed in San Francisco and Los Angeles over the last few months (see photo above). According to our sources, Schon approached the band with the idea for the video and they were all for it.

We're told the couple refers to the video as "Michaele and Neal's love story."

If Gerard Butler really did have mind-blowing sex with "Real Housewives of Beverly Hills" star Brandi Glanville -- as she proudly claims -- he doesn't remember it ... asking TMZ, "Who's Brandi Glanville?"

In case you didn't know ... Brandi -- Eddie Cibrian's ex-wife -- recently appeared on a talk show, announcing she once bumped uglies with Gerard for an entire week ... and it was so good, she rated him an 11 out of 10.

Rihanna and Chris Brown partied at the same club last night, fueling growing rumors they're back together.

The two singers left Greystone Manor -- a West Hollywood club -- separately, but they were both definitely there at the same time.

The protective order -- requiring that they have no contact with each other after Brown beat Rihanna -- was lifted a year ago.

Stacy Keibler just signed on with one of the biggest talent agencies in Hollywood ... she also happens to be dating George Clooney. Coincidence? We think not ...

Keibler is now repped by WME (aka William Morris Endeavor) ... nearly six years after leaving the WWE.

Her list of credits -- 2 episodes of "Chuck" ... 1 episode of "Psych" ... 1 ep of "How I Met Your Mother" and a cameo in "Bubble Boy" ... and several red carpet appearances with her SUPER POWERFUL BOYFRIEND.

WME reps some of the biggest names on the planet -- including Ben Affleck, Christian Bale, Russell Brand, Steve Carrell ... the list goes on and on ...

Funny enough -- Clooney is signed with WME's rival agency CAA.

Chad Ochocinco may have pulled his engagement to Evelyn Lozada out of the fire, but she's still on the fence about taking his last name when they walk down the aisle.

Evelyn was out in LA this week, and fully over her cheating fears about Ocho, saying ... "*hit happens and we worked it out."

As for changing her name -- sounds like Evelyn still needs some convincing.
